[newbie] Installing Mandrake 7.2 from ISO image

[Andrew Iovannisci]

Hello,

I am trying to install Mandrake 7.2 . I have downloaded the file 
mandrake72-inst.iso  and burned it onto a cd. I have also crated a floppy 
boot disc to start the installation.
When I restart my computer, Linux loads from the floppy,  and then I get 
the following error message:

' cd rom device does not seem to contain a Linux Mandrake cd'.

Obviously, I'm not doing something right. Can someone lend me a clue?
